ABSTRACT:
A combustion seal for sealing high pressure combustion gas within at least one cylinder of an internal combustion engine including a cylinder block, a cylinder head having a groove formed in its bottom face, a cylinder liner having a complementary groove formed in its top face, and a O-ring formed from a ductile material and positioned between and contacting each edge of the groove formed in the cylinder head and the complementary groove formed in the cylinder liner, wherein the O-ring is compressed when the cylinder head is secured on the cylinder such that the O-ring has multiple radial restraint points of contact with the edges. When securing the cylinder head onto the cylinder block, the O-ring is positioned between the grooves in the cylinder head and cylinder liner before a compressive force is applied. When the compressive force is applied, the O-ring deforms within the grooves such that part of the O-ring protrudes inside the grooves and part of the wire is deformed flat against the surface of the cylinder head and liner. High contact load pressure is generated at the points at which the O-ring contacts the edges of each groove, thus providing a seal for the high pressure combustion gas generated by the engine.
